Back in 2012 there was no question that ruby was the language of DevOps, then Ansible took over. Puppet was a true pain to work with, and through at least version 4, their language designers were simply wrong about what it meant to be a declarative language (you could only declare each resource once, they pretended/falsely believed that inference and/or unification were incompatible with declarative languages), but wow was it powerful to maintain dependable state on long lived servers

I'm sorry, but for me it seems that Go has is taking the lead in adoption rates for devops tooling.

Ruby isn't the go-to language there anymore... probably because GoLang compiles statically.

I think their comment still holds. Those are all tools that you use, and mostly don't care what language they're written in. When you've got to write Ruby, it was predominantly in the context of RoR.

I think also that dominance has mostly faded. When I think of languages that dominate devops now, I think of Go, and I say that as someone that dislikes Go.

Ansible is Python, Terraform is Go. Those are 2 giant projects in DevOps.

YMMV, but I've only seen Rails fans use any of those.
